1.c4 e5 2.Nc3 Nc6. The analogy of the favorite weapon of Boris - Closed Sicilian . colour reversed
3.Nf3 Nf6 4.a3.
4...d5! 5.cxd5 Nxd5. 6.Qc2. Logical move. White looks at the position of black and choose this option . 6.e4 ,the Chelyabinsk options ,is often played and the the Knight can retreat to b4 .
6 ... Be7. (6 ... Be6 7.e3 Bd6 8.Ne4 f5 9.Neg5 Bd7 10.Bc4 h6 11.Nf7! Kxf7 12.Bxd5+ Kf8 13.Bxc6 (13.d3!) 13...bxc6 (13...Bxc6!? 14.Qxf5+ Qf6) 14.d4 e4 15.Ne5 Bxe5 16.dxe5, whites were strong initiative, but not enough to win.
7.e3? (White should play 7.e4 because of 7 ... Nb6 8.Bb5 Qd6!)
7 ... a6
8.Bc4. Very aggressive approach and rarely played. 8.Be2, seeking Scheveningen variation. eg 8 ... 0-0 9.0-0 Be6 10.d3 f5 11.Rd1 Qe8 12.Nxd5 Bxd5 13.e4 Be6 14.exf5 Rxf5 15.Be3 Rd8 16.Nd2 Bd5 17.Bf3 Bxf3 18.Nxf3 Qf7 19 . Qc4 Qd5 20.Rac1 Rff8 21.Kf1 Kh8 22.Qxd5 and a drawn position Z. Izoria - M. Gagunashvili (Las Vegas 2006).
8...Nb6. Novelty. With the Knights Black has a good chance. .
9.Bd3. If White knew what awaited him, he probably would have move the bishop to e2
9 ... Qd7! Brilliant play! .
10.b3. Another standard maneuver that does not fit with the peculiarities of a particular position. Mystery maneuver of black queen is revealed in the form 10.Be4 f5! 11.Bxc6 Qxc6 12.Nxe5? 11.Bxc6 Qxc6 12.Nxe5? Qxg2!,And white position is bad.
10 ... f5. beginning of a Pawn storm!
11 ... g5!! Brutal!
12.exf5. Not doing much 12.h3 because 12 ... g4!
12...g4 13.Nxe5 Nxe5 14.Be4 Nc6.
15.Ne2 Bf6 16.Rb1. The more complicated the position, the greater the chances of mistakes by both side . 16.Bb2, perhaps objectively better. But it also makes it easy for black.
16 ... Qd6.
. 18.Rxh3! (Bringing out Rook to attack) 18 ... Bd7! (But black is not afraid of its attacks) 19.Rd3 (and still have to try) 19 ... Qf8! Strictly only move
20.Bxc6 ( 20.Re3 is no good, 20 ... 0-0-0!) 20 ... Bxc6 21.Re3 + Kd7. White managed to deprive the black kind castling. But it is not of importance
22.Bb2. White still not enough development.
22...Nd5 23.Qd3. trying to cling on to the game
23 ... Bxb2 24.Rxb2 Qxa3.
25.Rc2 Rae8 (an important element of artificial castling
